WILLIAM F. BARBEE, OF DES MOINES, IOWA.

CHURN.

Application filed April 24, 1912, Serial No. 692,981.

To all whom it may concern:

Be it known that I, WILLIAM F. BARBEE, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a new and useful Churn; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a new and useful churn having means, such as a spring motor or the like, for automatically operating the same.

One of the features of this improved churn is the provision of yieldable means for holding the cover upon the churn body.

Another feature of the invention is the )i'OClLlCtlOIl of means for raising and lowering the churn body or receptacle.

Another feature of the churn is the provision of a pitman adjustably connected to the churn dasher rod, and having an adjustable connection with a revoluble disk, whereby the stroke of the churn dasher may be varied.

A further feature of this improved churn is the governor mechanism for the spring motor, which has novel means,'adapted to be adjusted, for controlling the speed of the motor, and also including means for instantly stopping the motor.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a view in perspective of a cabinet with the improved churn and its operating mechanism inclosed therein. Fig. 2 is a section View through the cabinet, showing the improved churn and operating mechanism in elevation. Fig. 3 is an enlarged detail sectional view through the improved churn. Fig. 4 is a detail view showing the connection between the pitman and the revoluble disk. F ig. 5 is an enlarged detail view. Fig. 6 is a view of the governor for the spring motor. Fig. 7 is a detail view of the means for holding the rod 7 6 in adjusted position. Fig. 8 is a sectional view on line 8-8 of Fig. 6. Fig. 9 is a sectional view on line 99 of Fig. 8.

Referring to the drawings 1 designates the cabinet having a mirrored top 2, a pair of doors 3 and 4. The door 3 is provided with a glass 5 through which the churn may be seen.

Specification of Letters Patent.

Renewed September 10, 1913. Serial No. 789,172.

The cabinet 1 is provided with two compartments 6 and 7, the lower portion of the compartment 6 is subdivided by the partitions 8, thereby forming the compartment 9, in which a drawer 10 may be arranged. Between the partitions 8 a member 1.1 is arranged, through which a vertically disposed threaded opening 12 is formed, which receives the threaded rod 13. This threaded rod 13 supports the churn body or receptacle 14. By mounting the churn body or receptacle on the threaded rod 13, the same may be raised or lowered. The usual form of churn dasher 15 operates in the receptacle 14, and the piston. 16 of the churn dasher passes through the cover 17 of the receptacle 14, and is guided by the bearings 18 and 19 of the frame 20. This frame 20 is provided with tubular member 21, in which springs 22 are arranged. Extending into the tubular members are pistons 23 of the rods 24, the lower ends of which engage sockets 25 of the cover 17 of the churn receptacle. The springs 22 coact between the upper end of the tubular members and the pistons, so as to hold the lower ends of the rods 24 in the sockets, thus holding the cover 17 in a closed posit-ion. The tubular members are provided with elongated slots through which the thumb screws 27 pass, which are threaded into the pistons. The elongated slots are denoted by the numeral 26. By raising the cover 17, thus forcing the pistons upwardly in the tubular members, and then by tightening the thumb screw against the outer circumference of the tubular members, the cover or closure 17 may be held raised. The frame 20 is braced by the rods 28 and 29.

The piston rod 16 is provided with an arm 30, to which at 31 the pitman 32, is pivoted. The upper end of the pitman 32 has a pin extending through it, designated by the numeral 33 and is adapted to be threaded in any one of the apertures 34 of the revoluble disk 35. The apertures 34 are arranged spirally in the revoluble member 35. The revoluble member is carried by and rotatable with the shaft 36, which is mounted in bear ings of the cabinet.

In the compartment 7 the shafts 37, 38, 39, and 36 are arranged. These shafts constitute parts of the spring motor. Mounted on the shaft 37 is the gear 41, so as to move independently thereof. Connecting between the gear 41 and the shaft 37 is the spring 42 which may be wound by means of the crank 43 and the coiiperating bevel gears 44. The gear 41 meshes with the gear 45 on the shaft 38, on which is journaled the pulley 46, which in turn is belted to the pulley 47 by the belt 48. The pulley 47 is carried on the shaft 39. Also journaled upon the shaft 39 is a pulley 49, about which the belt 50 travels, which in turn travels about the pulley 51 of the shaft 40. A pulley 52 having a belt 53 traveling about it is journaled on the shaft 40. The belt 53 operates the pulley 54 on the shaft 36. By this gearing and spring 42 power is imparted to the shaft 36, the speed of which is governed by the governor 55. This governor includes the gear 56 and the brake wheel 57, with which brake wheel the brake shoe 58 cooperates, so as to retard the movement of the brake wheel and the shaft 36. This brake shoe 58 has a pinion 59 swiveled thereto, and which is in turn threaded to the rod 60 mounted in the bearing 61 of the bracket 62. This brake shoe is guided vertically by the portion 63 of the bracket, which portion extends through a groove in the brake shoe. Meshing with the pinion 59 is a worm 64, which is carried by the end of the rod 65. This rod 65 is mounted in bearings of the brackets 63 and the vertical partition 66 of the cabinet. A hand wheel 67 is mounted on the other end of the rod 65, whereby the rod 65 may be rotated. When rotated the pinion 59 is in turn rotated, thus causing the brake shoe to raise and lower, relative to the brake wheel 57 thus increasing or decreasing the frictional engagement between the shoe and the brake wheel, thereby governing the speed of the shaft 36. The gear 56 meshes with the pinion 68 of the sleeve 69, which carry the cen trifugal balls 70 of the governor. The sleeve 69 is mounted in a bearing 71, which is braced by the braces 72, to the horizontal supporting shelf 73 to the cabinet. The balls indicate the speed of the shaft 36, and by rotating the rod 65, so as to operate the shoe on the brake wheel, the speed may be increased or decreased. The gear 56 also acts as a brake wheel, the same being provided with an annular fiber band 74, with which the brake arm 75 engages. This brake arm is movable with the rod 76, which is rocked in one direction or the other by the lever 77, there being a rack 78, for

holding the lever 77 in adjusted positions. \Vhen the brake arm 75 is thrown in contact with the fiber band of the gear 56, the shaft 36 is substantially instantly stopped.

When the operator has finished churning, the churn body or receptacle 14 may be lowered, and the cover 17 raised, after which the receptacle may be removed, thus permitting its contents to be emptied.

The invention having been set forth, what is claimed as new and useful is: I

1. In a device as set forth, a frame having a cross support, a churn including a cover adjustably mounted on the support of the frame, said frame having a cross bar and provided with brackets above the bar, said bar and the bracket having tubular connections, the cross bar having a bearing for the dasher rod of the churn, while one of said brackets is provided with an additional bearing for said dasher rod, means for holding the cover in place on the churn, said means comprising rods having pistons in said tubular connections, springs interposed between the pistons and the upper end of said tubular connection.
